I have Grafana dashboards with “Stat” components and I try to change the display names.
I’ve found only one working way: add a field override using regexp. All works, but I can’t use groups in regexp. I want to do something like:
My_own_metric_(.+_.+) -> $1
I’ve tried a lot of different way to write it: $1, \1, ${“\1”},..
But I was only able to change it on static text.
I’m using Grafana-8.3.3-Ubuntu version.
Maybe someone knows a solution?
Apparently it's not possible to use groups in field override.
What you need to do is add an "operation" in the query itself:
+ Operations > Functions > Label replace
and set the legend:
Options > Legend > Custom > {{yourlabel}}.
So, an example for a straightforward mqtt exporter query,
changing the displayed label
from $SYS/broker/clients/maximum
to maximum:

I have different Grafana dashboards build on Graphite datasources.
And add variable with such values:
grp1,grp2,grp3,grp4
Now I can choose any group in dropdown menu and it works perfectly
Also I can write in the query body something like:
{grp2,grp4} to get sum of this two groups.
My question - how to make variable value that combine several possible values?
I mean I want to add to dropdown menu more options like some combinations
I tried the same way in Variables menu:
grp1,grp2,grp3,grp4,{grp2,grp4}
but this doesnt works - it create values like {grp2 and grp4}
Also I tried to use Alloption here in the menu, but without success.
You need to escape comma with \, e.g.:
grp1,grp2,grp3,grp4,{grp2\,grp4}
so {grp2,grp4} will be one item in this case.
I am building Grafana (4.1.1) graphs with a Prometheus (1.1.2) backend, and am trying to use Templates to select/deselect certain sub-sets of metrics on a dashboard. I have a template variable called "$POP" which describes my city locations, and a template variable called "$Resolver" which describes the type of resolver I am using ("unbound" or "pdns" are the possible string results.)
I have these two metrics like this that work quite well currently selecting on the various values in $POP:
irate(dnsdist_recursor_main_servers_unbound_drops{env="prod",loc=~"$POP"}[1m]) > 0
irate(dnsdist_recursor_main_servers_pdns_drops{env="prod",loc=~"$POP"}[1m]) > 0
Putting aside for the moment that instead of labels the selection criteria are embedded in the metric name (I know it's not ideal but this is just an example of larger problem sets so please do not suggest how I can use labels) I would like the following results:
When (~"$Resolver" == "unbound") I would like to show the first metric (dnsdist_recursor_main_servers_unbound_drops) and when (~"$Resolver" == "pdns") I would like to show the second one (dnsdist_recursor_main_servers_pdns_drops) and when both are selected I'd like to show both metric set data. Basically, I hope to have an on/off visibility trigger for a metric that is keyed to my $Resolver template value.
How do I create a boolean such that the metric is shown or not shown based on the setting of the string value in the templated setting of $Resolver? The trick here is that the selection criteria is in the metric name, not a label, which is really stumping me. I tried "bool" modifiers but was never able to get anything to work on string equality tests. I'm sure it's just a syntax issue but examples are thin on the ground.
What you can take advantage of here is that there's no uniqueness restriction on label selectors, so you can do {resolver="$resolver",resolver="unbound"}
I am using GWT ValeBox with GWT Renderer to show amount with $ as prefix.
Now I want not to allow user to type any thing before dollar sign. I tried various GWT event handlers like ValueChangeHandler and some others but unable to achieve goal.
Still struggling for it. If anybody know good solution for it, please share here.
Regards,
The easiest would be to not include the currency as part of the value, but next to the field.
Alternatively, you could replace the value with a numeric-only value on focus, and reformat it as a currency on blur.
Couple of solutions:
Use a label before the valuebox. Label value will be $ and valuebox will contain the numeric value.
You can use empty text in the valuebox. Empty text will specify user to enter $ value.
I'm currently trying to develop an Eclipse Plugin to support code replacement, like what the default content assist in Eclipse do. What I want to implement is something like "insert argument names automatically on method completion with visualized box around the argument" and I can "use the Tab key to navigate between the inserted names" and "while navigating, list of optional variables for current argument can be displayed and be chosen".
In short, it comes to two questions:
How to add the visualized box around the already existed variable or even Java keywords that need replacement? And at the meanwhile I can use Tab key to switch between these boxes.
How to display a list of candidates to select from when I trigger on the box?
By now I only figure out the extension point : org.eclipse.jdt.ui.javaCompletionProposalComputer may be useful, but I have no idea where to start at? Thanks in advance.
Oh, finally I've solved it myself...
For the 'box', it should be the LinkedModeModel, this class should work with LinkedPositionGroup and LinkedPosition to add mutiple boxes. And we should use LinkedModeUI to set it up.
For the content assistant, there's no need to use the extension point. There is a ProposalPosition class which extends LinkedPosition for you to add your proposals for the 'box' in its constructor. And we can simply use the CompletionProposal to construct a ICompletionProposal array as the argument of ProposalPosition's constructor.
I found in typo3 admin side(/typo3), you can have two ways to set up TS,
you can set up through template->root, I think TS here will affect the whole site.
you can set up through template->certain page, it will only affect this page.
So my question is:
If I want to find where(which page) has TS setting such as : code = LIST, how could I do?
Use Web > Template module it has tools, you can for an example use Template Analyzer for the search
Try querying the database in phpMyAdmin or similar. The following looks in Template Setup:
SELECT pid, config, constants
FROM sys_template
WHERE config LIKE '%code = LIST%'
Replace config with constants to look in Template Constants. pid is the page ID.
If it is not set in the TypoScript, it perhaps has been set in the plugin itself. Just check the plugin content element itself.
In the Template module, go to the page where the setting is in effect.
Use the TSOB (Typo Script Object Browser) to search for "list":
This must show you all TS for this page that contains "list".
If you don't see the setting you can run a cmd/ctrl-F Search over the entire results.
You would have to search for "[code] = LIST".
Which will lead you to the following entry:
Hovering over the label will produce the above tooltip. Copy the line number.
Now change to the Template Analyzer. Here, you can click through all cascading templates and search for the line number:
This is definitely the line that sets that value.
From the "Template hierarchy" tree you will easily find the template that contains the setting.
